Hi, I accidentally bumped into my PC and it instantly turned off. After restart there was just black screen. I tried removing graphics card and connecting monitor to the motherboard, it works.

So I presume it's dead or something on the motherboard regarding GPU is dead. How is it possible I somehow blew that thing by stumbling over the PC case? Is there any way to fix it? The hard drive also started making some funny sounds and I'm on quite a budget right now. Not sure if I can afford to buy both new hdd+gpu.
